# Will we feel right up inside the airplane if the airplane accelerates toward earth at 20m/s^2?

Suppose you are in the airplane and the airplane falls toward the earth with acceleration of $20m/s^2$(double of gravitational acceleration $g$). This double acceleration by airplane will cancel the gravitational acceleration and create gravitational acceleration upward from the earth. If this happens, you will be pushed to the ceiling of the airplane if there is such a airplane that falls vertically from its rest position. While falling, the environment in the airplane will be the same as on the earth because in both case you will be pushed in the direction of the acceleration. My question is if this happens, will we feel right up while while being pushed to the ceiling of airplane? Will we feel just standing on earth?
